Leaked photos have already shown the brand new BMW 4 Series and its gigantic grille in all its glory, so the official reveal of the production version seemed to be imminent. According to BMW Blog's sources, we don't have very long to wait because the new BMW 4 Series will reportedly make its big debut in June.

The timing would make sense, as production is also expected to start in July. A June reveal also suggests BMW was planning to show the new 4 Series to the world at the 2020 Detroit Auto Show, but this obviously won't happen now since the show has been canceled due to the coronavirus pandemic and will return in June 2021.

Instead, the BMW 4 Series will break cover online, but it's going to be a long time until we get to see it in the metal since there are currently no major auto shows scheduled for this year.

As we've seen in leaked photos and spy shots, the new BMW 4 Series will have a bold new look inspired by the BMW Concept 4. Its new kidney grille will be significantly larger than its predecessor's to help distinguish the new 4 Series from the 3 Series. The new design direction was very polarizing, but we're hoping the grille on the production 4 Series won't look as jarring as the concept's. As for the interior, prototypes have been spotted with a very familiar cabin design carried over from the BMW 3 Series.

Curiously, however, sources claim there will also be some "interesting changes" but didn't provide any further details, so the design appears to have evolved since our last look inside the new 4 Series prototype.

In terms of powertrain options, the BMW 4 Series will pack a 2.0-liter turbocharged four-cylinder producing 255 hp in the base model, while the hotter M440i will use a 3.0-liter turbocharged inline-six with 380 hp on tap. The latter engine will also carry over to the new M4 tuned to produce between 440 hp and 500 hp. After the BMW 4 Series Coupe debuts in June, the new 4 Series Convertible and Gran Coupe should be unveiled later this year followed by the new M4 next year.
